This scale is the deepest of the three I currently offer. This drum is tuned with A4 set to 432 Hz rather than the normal 440 Hz, which makes each note about 30% deeper. The notes are A#3, C4, D, F, G, A#, C5, D. Includes a pair of birch-handled, rubber ball mallets that are custom made for providing clear tones and little impact noise. This is my favorite scale currently. I find it very soothing and the deeper scale is more resonant than the scales in C, which is made slightly more resonant with the 432 Hz tuning. The price includes a pair of custom made mallets and U.S. shipping.
